Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Integer overflow (CVE-ID: CVE-2022-25147)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow within the apr_base64() function. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Information disclosure (CVE-ID: CVE-2023-34981)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to HTTP headers are not set in a response. A remote attacker can send a specially crafted HTTP request and gain unauthorized access to sensitive information on the system.


3) Resource exhaustion (CVE-ID: CVE-2020-7760)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when processing regular expression. A remote attacker can trigger resource exhaustion and perform a regular expression denial of service (ReDoS) attack.


4) Untrusted search path (CVE-ID: CVE-2023-38408)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to usage of an insecure search path within the PKCS#11 feature in ssh-agent. A remote attacker can trick the victim into connecting to a malicious SSH server and execute arbitrary code on the system, if an agent is forwarded to an attacker-controlled system.

Note, this vulnerability exists due to incomplete fix for #VU2015 (CVE-2016-10009).


5) Buffer overflow (CVE-ID: CVE-2023-3824)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the phar_dir_read() function. A remote attacker can force the application to open a specially crafted .phar archive,  trigger memory corruption and execute arbitrary code on the target system.
